Abstract:
Presents a conceptual model for the behavior of structural walls subjected to lateral load reversals. The primary feature of the model is a reduction in shear strength with increasing levels of deformation. Measured and calculated data from structural walls are evaluated to determine conditions for which the strength and deformation capacity of a wall may be limited by the residual shear strength.

SP-162 This fact filled symposium, developed in honor of Mete A Sozen, contains 17 highly informative papers. A spectacular addition to all reference shelves. This symposium took place at the ACI Fall convention in Tarpon Springs, Florida in October of 1994. The Sozen Symposium consisted of three sessions with eighteen speakers. The symposium and this SP volume were organized to permit Mete's students and colleagues to honor and thank him for his council and guidance during their studies at the University of Illinois.

The development of concrete offshore structures is illustrated by briefly describing the background for their functions, the development of structural design, brief examples of concrete research and research results, industry research projects, and international standardization. Figures and main specifications of typical structures are shown.

An evaluation of the implications of the structural system selected for reinforced concrete buildings with three different plan layouts and four different heights (5, 10, 15, and 20 stories) was performed as part of the calibration of the update of the Colombian Seismic Code (10). The buildings had varying amounts of structural walls. In total, 72 buildings were studied. Expected performance of the buildings under the code design earthquake was evaluated using elastic and inelastic procedures. Using the amount of concrete and reinforcing steel for all the buildings and prevalent material and labor prices, a cost of the structure per unit area was determined. Conclusions with respect to behavior and cost implications were obtained for the parameters studied for the different buildings.

Following the strong earthquake in Chile on March 3, 1985, an intensive study was conducted to ascertain why the large inventory of moderate rise buildings in the coastal city of Vina del Mar performed so well during the earthquake. The major findings were that the vast majority of the buildings in this coastal city had a high wall area to total floor area ratio and that the reinforcement detailing in the boundaries of these walls were considerably less than required by U. S. codes. Analytical studies indicated that the high percentage of walls led to significantly lower drifts under severe seismic shaking, thus lowering the ductility demands on the walls. At lower levels of ductility demand, experimental results have demonstrated that wall boundaries did not need special detailing of transverse reinforcement. The findings from the series of research studies following the Chilean earthquake have led to modified U. S. design procedures that relate the need for special detailing in wall boundary elements to expected strain levels along the compression edge of the wall. The expected strain levels are determined based on the aspect ratio of the wall and the percentage of wall area to floor area used in the building.
